Thank you, ACK-J - this little extension works well. However, I've only rated it 3 stars because sometimes it proves to be a somewhat counter-productive annoyance. This plugin really, really needs a "whitelisting" option. For example, I can't log in and use box(dot)com and a couple of other sites/services that I use to backup my files online, unless I remember to temporarily disable 'Port Authority'. Please add a whitelisting option - that will make it a fully 5 star extension.
